    Re: Oh how I wish

    ^shyone-
    I have been following your conversation with respect to volume normalization while ripping with dMC (dBpowerAMP Music Converter) using DSP effects including EQ and volume normalization. As I understand Cuparboy's issue, it is raised in reference to the Auto Volume Normalize feature of the dBpowerAMP Audio Player (or dAP), although this was not initially clear. While these features serve a related purpose, it has always been my understanding that they do so independently of one another. I don't believe I have ever heard a report of distortion or clipping using dAP's Auto Volume Normalize function.

    I suppose it is true that if dMC's volume normalization function worked better and if one only dealt with material one had personally ripped through dMC that the dAP Auto Volume Normalization would be superfluous. But I don't personally believe and it has not been my personal experience that faulty volume normalization on dMC's part is the principal reason for turning to the dAP Auto Volume Normalization function.

    My short answer is that I don't see the link between Cuparboy's post and your posts on volume normalization. I do respect your reports on the volume normalization issue and the research you have devoted to this issue.

    Best wishes,
    Bill

      (Good to see you're back xoas)

      I think the only time folks might encounter a clipping or distortion problem with dAP is if they increase the Volume Boost control of a track to the maximum side of the range from within MMC.
      Spoon recently shed a bit more light on this subject in another thread http://forum.dbpoweramp.com/showthre...+normalization saying that AVN from MMC could increase some quiet files levels, but could not decrease louder files. Some albums are a lot louder than others.

      My strategy is to decrease the loudest tracks with MMC's Volume Boost control to match 'listening' levels of quieter tracks. I would probably start by concentrating on whole albums at a time using the right click "Edit Tag" option on those tracks (while holding down the Ctrl Key) as xoas suggested earlier, which can reset numerous tracks at a time.

      Hope this helps.

        I have recently re-set the "Auto Volume Boost" feature on all of my collection, all 5600 plus songs at once. Simply highlight all of your files, right click to edit tag, and click on the little green A.
        The only downfall to that is it seemed to put some kind of tiny hidden attribute in the file. I might be way off on that one, but I have a removable hard drive to back up all of my music files on. I use a program called "SyncBack" that scans for changes between the internal hard drive and the external (removable) one, when I re-set the "Auto Volume Boost" and ran SyncBack, I ended up re-copying all of my 5600 songs to the removable drive. Normally SyncBack only picks up on any new music I have added, or if I have edited the tag by adding a missing date or album name. Still glad I did it, even if it took some time to back it all up.

          Upon further review, I've found this method is not working as first thought.
          Decreasing MMC's Volume Boost slider on any chosen song will decrease it's overall volume only while you are listening to it and making the changes.
          Any subsequent replays pop the volume level right back up where they were, even though the Boost slider remains where you set it.
          (Tests conducted with EQ turned Off while monitoring StudioPro VU's, using dAP Release 3 Beta 6)

          A method that does seem to work is turning the EQ 'ON' and decreasing the EQ Boost slider to a desired level (below VU 0dB) and saving the EQ settings through the EQ 'SAVE' button (Auto Equalizer/Current Track/ or Current Album/Artist/Genre).

          The only drawback here is that there seems to be a bug that prevents the EQ boost from returning to the previous (normal) level I have set for the rest of my music collection. (I use the 20-band equalizer exclusively).
          Hope this is helpful.
